The 3D models of the avian skeleton and respiratory system were created with Autodesk Maya. A pigeon skeleton was used as reference. The individual elements of both the skeleton and respiratory system were modeled separately and then brought together.

The muscles of the forelimb were modeled and rigged using Maya Muscle Builder.
